Application filed. May 11, 1914. Serial No. 837,795.

the Kingdom of Italy, have invented newand useful Improvements inMountings for Locomotives and Railway-Cars, of which the following is aspecification.

The present invention proposes an improved mounting for locomotives andfor railway cars in general, and it resides in the provision of aswinging joint between the parts which support the locomotive or carwhich is so constructed as to secure the independent movement of thesaid parts and to avoid, as far as possible, all causes of strains, wearand breakdown that might arise either from the different relativepositions which such parts may take, from jolts and sudden obstacles, orfrom the relative asynchronous oscillationsof different amplitudes ofthe said parts with respect to one another.

The annexed drawings show by way of example an embodiment of theinvention as applied to a locomotive.

Figure 1 is a side view of the said locomotive. Fig. 2 is a plan View ofthe boiler supporting girder. Fig. 3 is a plan view of the two truckbodies. Figs. 4 and 5 are sections through a swinging joint at rightangles with one another. Figs. .6 and? are two eX- ternal views of theswinging joint;

It is obvious that the invention can be applied, in like manner topassenger and -freight cars and, generally, in any connection in whichswinging joints are required.

In Fig. 1 are shown diagrammatically the girder 1 carrying the boiler 2,which is shown in dotted lines, the locomotive casing 3, and the twotruck bodies 4: and 5, which, in the case of locomotives, together withthe wheels and gear (not shown on the drawing) make up the two trucks.To girder l 4 are fixed the frames 6-6; to the two truck frames 4 and 5are fixed the two frames 7-7. The support or suspension (on the drawinga support is shown) of the rigid girder 1 on or from the two truckbodies l and 5 is efiected by means of interposed springs, while theswinging joints are obtained through two specially-constructed bolts 8-8which, however, are so arranged as to carry no load. The cylindricalupper portion 9 of each of these bolts can be fixed either to a frame 6,or to a frame 7 (on the drawing it is secured to frame 6) where as thespherical lower portion orhead 1.0 is

mounted to turn in a socket 11 which is arranged in a chamber 12provided in the frame 7.

In Figs. 4 to 7 is shown diagrammatically one of the two metallic frames6-6 secured to the sides of girder 1; these frames 66 with their saddleshaped surface 13 formrests for boiler 2. The'surfaces 14 affordsupports for the slides 15 (on the drawing two are shown for each frame6). In each slide 15 there are recesses 16 (on the drawing four recessesare shown for each slide), 1n which bushings 17 are fitted, provided 1with spherical sockets 18 which receive the spherical heads of the bolts19, these bolts having their shanks slidably mounted in openings 20 inthe two frames 7-7. The lower ends 21 of bolts 19 are carriedrespectively by studs22 whose heads 23 cause the superinc'umbent weightto be taken up by the springs 24:, which latter in turn rest (with orwithout the interposition of washers 25 or the like) on studs 26 screwedinto the frames 77 in order to permit said springs to be readily andeasily replaced.

The portion 9 of each of the bolts 8 is shown as being held in place byclamp 29 and bolt 28.

The cylindrical external surface 30 of socket 11 has a sliding fit inthe chamber 12.

In the arrangement shown, the slots 32 in the spherical head 10 of bolt8 enable the lubricant to flow therethrough'while the bolt is turning,the lubricant being caught in a dished plate located at the bottom ofchamber 12.

The form, number and relative position of the various parts may vary,the invention not being limited to any of them.

.Having now described my invention and how the same is to be carriedout, what I claim as my invention, is:

the girder and provided at its lower end with a spherical head, and amember slidable vertically in the chamber in the adjacent truck frameand provided with a spheritatably fits; and yielding supporting devicesintermediate said girder and said trucks.

' girder ends 2. A mounting for locomotives and railway cars comprisinga girder Whereon the body of the locomotive or car is adapted to rest; apair of trucks disposed beneath the end portions of the girder, saidtrucks and constituting companion parts, one of which is provided with avertical chamber and with a socket element slidably fitting therein; apair of vertical bolts provided at one end with spherical headsrotatably fitting in the respective socket elements and having theirother ends attached tothe adjacent girder ends; and yielding supportingdevices intermediate said girder and said trucks.

3. A mounting for locomotives and railway cars comprising a girderwhereon the body of the locomotive or car is adapted to rest; a pair oftrucks having swinging-joint connections with the end portions of saidgirder, each truck being provided with a plurality of vertical openings;a plurality "against one face of the of spring-controlled bolts movableendwise through said openings and rounded at one end; and bushingscarried by said girder and provided with sockets wherein the roundedends of said bolts fit.

4:- A mounting for locomotives and railway cars comprising a girderwhereon the body of the locomotive or car is adapted to rest; a pair oftrucks having swinging-joint connections with the girder, each truckbeing provided with a plurality of vertical openings; spring-con:trolled bolts movable through said openings and. rounded at one end;slides arranged with recesses; and bushings fitted in said recesses andhaving sockets for the reception of said-bolt ends.

In testimony whereof I hereunto affix my signature in the presence oftwo Witnesses.
